Tomas Ekbom Hans Hjortsberg Carl-Johan Hjerpe Bengt S5vbark Ingvar Landalv March 2000 BioMeeT-project Preamble In the earlier study, The Altener-project “BAL-Fuels” (Biomass derived alcohols for automotive and industrial use; contract no. XVII/4 1030/Z/95-124) the technology status for production of biomass based alcohols (methanol and ethanol) was reviewed and updated. The study also demonstrated the feasibility of using methanol emulsified in diesel oil to achieve reduction of NOXand particulate from diesel engines. In this study, the Altener II-project “BioMeeT” (Planning of Biomass based Methanol energy combine —Trollhattan regio~ contract no. XVW4. 1030/Z/98-368) a second step will be taken towards realisation of a concrete plant for production of motor fhels (methanol/DME), fiel gas, electric power and heat from mainly lignocellulosic feedstocks via primary conversion by gasification. This conversion route shall be seen as step to produce “clean” secondary energy carriers for a transition to long term sustainable energy system. The project is headed by the Trollhattan Municipality (Sweden) with local interested parties including Trollhattan Energy, Saab Automobile, Volvo Aero, Volvo Truck, Vattenfall Trollhattan. European participants are Air Products PLC (UK) and Methanex Europe S.A. (Belgium), The Swedish National Energy Administration lends financial support. Ecotraftlc R&D AB is contracted as project leader and administrator and works together with the engineering consulting company Nykomb Synergetic AB (Stockholm). The BioMeeT-project covered by this final report comprises final results. An intermediate report was published in early September 1999, covering the phases 1 and 2, and describes the potential supply of biomass raw materials and markets of different energy carriers (motor fiels, firing fiels, electric power, district heat) respectively. The data have been mapped for two regions, the “three-city”- region (municipalities of Trollhattan, Uddevalla, and Vanersborg) and the entire county of Vastra Gotaland. As background the situation in all Sweden is given. The knowledge basis was used to study in phase 3 and 4 how a bio- based conversion plant (energy combine) based on primary gasification can be configured to suit the replacement of fossil-based energy carriers on the markets. In phase 3-4 engineering work, with assistance of sub-contractors, was performed to confQure a plant and discuss its efficiency, flexibility to meet seasonal variations, and preliminary economics. The contributions, technical, commentary and financial, from all participants are gratefully acknowledged as an invaluable input to the study. The study results shall contribute to forma decision basis for fi.wtheraction.
